There are plenty of photo cropping applications for iOS. Here's a new wrinkle that caught my eye. The app is called AntiCrop, and it's a US $0.99 universal iPad app that does the opposite of cropping a photo. It actually adds new data to the top and sides of an image, allowing you to reframe something that didn't come out right in the first place.
AntiCrop is kind of the reverse of Photoshop's content-aware fill. Content-aware fill allows you to take something out of a photo by blending in nearby pixels. Anti-crop works at the edges, and pretty accurately gives you new data that doesn't look especially fake or blended in after-the-fact.
